Vorticity Modeling of Blade Wakes behind Isolated Annular Blade-Rows: Induced Disturbances in Swirling Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general analysis is proposed for studying the fluid-mechanical behavior of blade wakes from an annular blade-row in highly swirling flow. The coupling between the centrifugal force and the ...
Control of the Unsteady Flow in a Stator Blade Row Interacting With Upstream Moving Wakes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational approach, based on a spectral-element Navier–Stokes solver, has been applied to the study of the unsteady flow arising from wake–stator interaction. Direct, as well as turbulence-model ...
Effect of Blade Passage Surface Heat Extraction on Axial Compressor Performance
